Abstract
【解決手段】この発明に従った横型JFET10では、バッファ層11は、SiC基板1の主表面上に位置し、p型不純物を含む。チャネル層12は、バッファ層11上に位置し、バッファ層11におけるp型不純物の濃度より高い濃度のn型不純物を含む。n型のソース領域15およびドレイン領域16は、チャネル層12の表面層において互いに間隔を隔てて形成され、p型のゲート領域17は、チャネル層12の表面層においてソース領域15およびドレイン領域16の間に位置する。バリア領域13は、チャネル層12とバッファ層11との境界領域において、ゲート領域17の下に位置する領域に配置され、バッファ層11におけるp型不純物の濃度より高い濃度のp型不純物を含む。
【選択図】図1
Description
図1を参照して、本発明に従った横型接合型電界効果トランジスタ(横型JFET)10の実施の形態1を説明する。図1に示した横型JFET10では、SiC基板1の上にp-型のバッファ層11が形成されている。このバッファ層11の上部表面層(SiC基板1側の表面とは反対側の表面層)において、導電型がp型であって厚みdを有するバリア領域13が形成されている。バリア領域13は、後述するゲート領域17下に位置する領域に配置されている。バリア領域13のp型不純物濃度は、バッファ層11のp型不純物濃度よりも高い。バリア領域13の上に、チャネル領域14を含み、導電型がn型のチャネル層12が形成されている。また、チャネル領域14の上に、p+型の(つまり、導電型がp型であり、p型不純物濃度がバッファ層11やバリア領域13におけるp型不純物濃度より高い)ゲート領域17が配置されている。ゲート領域17を間に挟むように、n+型領域である(つまり導電型がn型であり、n型不純物濃度がチャネル層12におけるn型不純物濃度より高い)ソース領域15と、n+型のドレイン領域16とが配置されている。
図3を参照して、本発明に従った横型接合型電界効果トランジスタ(横型JFET)40の実施の形態2を説明する。図3に示した横型JFET40は、いわゆる横型のRESURF‐JFET(REduced SURface Field Junction Field Effect Transistor)であって、基本的な構成は図1に示した横型JFET10と同様であるが、チャネル層12の表面層においてソース領域15、ドレイン領域16およびゲート領域17の間に導電型がp型のRESURF層41が形成されている点が図1に示した横型JFET10と異なっている。RESURF層41のp型導電性不純物の濃度は、バッファ層11における導電性不純物濃度より高くなっている。また、RESURF層41のp型導電性不純物の濃度は、バリア領域13における導電性不純物濃度より高くなっていることが好ましい。このようにすれば、ゲート領域17とドレイン領域16との間の領域において、空乏層がRESURF層41側から上下方向に伸展するので、当該領域での電界分布が、ちょうど平行平板型のコンデンサに近い等電界と電界分布となる。このため、RESURF層41を形成しないJFETに比べて耐圧を保持したままオン抵抗を低減することが可能になる。そして、当該RESURF層41を備える横型JFET40においても、図1に示した横型JFET10と同様にバリア領域13が形成されているので、図1に示した横型JFET10と同様の効果を得ることができる。
